[ 14 C 4 ]GA 53 , [ 14 C 4 ]GA 44 , and [ 2 H 2 / 14 C 4 ]GA 19 were injected separately into seedlings of rice ( Oryza sativa) using a dwarf mutant ( d 35 ) that has low levels of endogenous gibberellins (GAs). After 8 h incubation, the shoots were

[17-(14)C]-Labeled GA(15), GA(24), GA(25), GA(7), and 2,3-dehydro-GA(9) were separately injected into normal, dwarf-1 (d1), and dwarf-5 (d5) seedlings of maize (Zea mays L.). Purified radioactive metabolites from the plant tissues were identified by
The cultivation of rice in Japan has suffered from damage caused by baka nae disease, in which rice seedlings show abnormal growth (elongation) as the result of infection by a plant pathogen. Investigation of the taxonomy of this pathogen led to th

[17- 13 C, 3 H 2 ]GA 9 was administered to 4-week-old seedlings of normal, dwarf 1 and dwarf 5 seedlings at the 3–4 leaf-stage. After 12 or 24 hr incubation, shoots were harvested, extracted with methanol and the extracts purified by solvent partit

This paper reports the identification of gibberellin A 1 (GA 1 ), GA 17 , GA 19 , GA 20 , GA 29 , and GA 53 from extracts of normal (wild-type) maize callus using full-scan GC-Mass Spectrometry and Kovats retention indices (KRIs). In addition, eviden

The purpose of this study was to demonstrate the metabolism of gibberellin A20 (GA20) to gibberellin A1 (GA1) by tall and mutant shoots of rice (Oryza sativa L.) and Arabidopsis thaliana (L.) Heynh. The data show that the tall and dx mutant of rice a

The [6-2H]glucosyl ester of [17-13C,3H]gibberellin A20 (GA20) was injected into light-grown 14-day-old seedlings of normal, dwarf-1, and dwarf-5 maize (Zea mays L.). The plant material was extracted 24 h later, and the extracts were purified by solve

Young shoots of normal maize (Zea mays L.) were used to determine both the stepwise metabolism of ent-kaurene to gibberellin A(12)-aldehyde and the endogenous presence of the members in this series. Each of the five steps in the sequence was establis

Combined gas chromatography-mass spectrometry (GCMS) was used to identify and quantify specific cytokinins from Porphyra perforate J. Ag. and Sargassum muticum (Yendo) Fensh. The level of isopentenyladenosine was estimated to be 0.6 μ·kg−1 fresh
